City tests new weapons in fight against potholes

In the latest round of Boston versus potholes, the city is bringing in the big guns: a Silly Putty-like material encased in portable plastic bags invented by college students. Shape-shifting goo that hardens instantly under pressure... The company's founders, recent graduates of Case Western Reserve University in Cleveland, believe the pliable bags can serve as a fix for a few hours or days, preventing damage to passing vehicles before crews can make a permanent repair.
